Any Suggestions on How to Remove Stripped Screws? (hayward / castro valley)

Hello, I need to replace my door locks but the screws are stripped. I think I made the situation worse by trying to remove them myself with an extractor. I first tried using rubber bands but that didn't work. Any other suggestions? Do I need to call a locksmith for this? I also thought of gluing one of the extractor on to the screw head but haven't tried that, still need to find like a metal glue or something. Thanks in advance for any suggestions you can provide.
